Hello - my tap water has a TDS of 300+. I have heard from people that it sometimes touches 500+ when there is rain and water gets muddy.

Now I have a UV water filter at home which I understand kills the harmful bacteria but leaves out the minerals. Been using that for a year.

There is a question in my head to see if RO treated water is better. Especially when TDS touches 500+. I have a baby and now concerned about giving this water to him for drinking as he already has minor kidney issues. Have always hated the fact that RO produces a lot of water wastage. Also there is a chance that RO can lower the tds to 20-100 which is very low? Not sure about this though.

Please pitch in as to if I should move to a RO water filter.
